PW 50 foot actuated brake?

I saw a PW 50 for sale somewhere and the list of add on parts listed that it had a foot actuated rear brake.

Does anyone know of an aftermarket manufacturer that supplies kits to convert the handle bar operated brake to a rear foot brake?

My son has a small 4 wheeler that has a rear brake. I would like to stay with the same brake set up on his first dirt bike.

He just turned 3 and is not tall enough for the other larger 50cc bikes.

Any info on converting the rear brake on the PW would be greatly appreaciated.

Thanks...

FruDaddy, thanks for the info.

That would be great if I could just order factory parts.
